Support Tube for a Filter Element - A filter element has a support grid structure with a first axial end and a second axial end. A filter medium surrounds annularly the support grid. The support grid has structural web members that are connected and form a hollow-cylindrical grid structure that surrounds a cylindrical interior. At least three of the structural web members or structural web sections connect to each other to define a through opening. A fluid flow is enabled in radial direction relative to a center axis of the hollow-cylindrical grid structure through the through openings. A first average opening cross-section of the through openings in a first region adjacent to a first axial end is greater than a second average opening cross-section of the through openings in a second region adjacent to the second axial end.

Process for controlling a friction clutch - The invention relates to a process for controlling an automated friction clutch with a wear adjustment device that adjusts extended clutch stroke by a discrete magnitude through the wear of friction lining at maximum transmittable torque of the friction clutch. To guarantee safe self-adjustment, also during a long operation period under the maximum clutch torque, under specified preconditions, for instance, during the start of the internal combustion engine and without gear engagement, the friction clutch is closed for maximum clutch torque.

DUAL CLUTCH - A dual clutch, which has a first friction clutch pulled by a first lever actuator and a second friction clutch pushed by a second lever actuator. The lever actuators each have a lever that is spring-loaded on one side and lever tips which are moved by a bearing block. The bearing block can be moved radially with along a profile of the lever to set a variable contact point of the lever between a rigid base plate and the lever to act on actuating hearings of the friction clutches. The bearing block is actuated by force application in one of the radial directions of motion by a drive controlled by a control unit in an automated manner. The drive of both lever actuators is formed by a pneumatic controller. In each drive a piston is movable in a housing and is connected to the bearing block by a piston rod.

METHOD TO CONTROL A MOTOR VEHICLE DRIVETRAIN - The invention concerns a method for controlling a motor vehicle drivetrain which comprises a drive motor, a multi-step, automated change-speed transmission and an automated separating clutch arranged between the drive motor and the transmission, and a shifting device with a selector lever which can be moved at least from a particular position in an upshift direction (“+” direction) for manually initiating an upshift and in a downshift direction (“−”) for manually initiating a downshift, and in which the transmission and the separating clutch can be controlled by a transmission control unit which is connected at least to a speed sensor, a brake pedal actuation sensor and a selector lever actuation sensor, such that when the motor vehicle is rolling with its drivetrain open the closing of the drivetrain is initiated by actuating the selector lever.

MOUNTS FOR ELEMENTS OF WATER OR HEATING INSTALLATIONS - A mount for elements of a water or heating installations is provided that includes a base body and a retaining clip that extends around one of the elements and releasably attaches it to the body. The base body and retaining clip are shaped to fit the elements. The retaining clip is U-shaped, has two legs and is made of a resilient, sound-damping plastic. The ends of the legs are bent back in a V shape and first detent projections are formed on the outside of the leg ends. The base body has openings matched to the legs. Formed on the inner wall of the openings are second detent projections, which cooperate with the first detent projections. The ends of the legs are designed to be manipulated by hand.

DEVICE AND METHOD FOR ERROR MONITORING FOR UNDERCARRIAGE COMPONENTS OF RAIL VEHICLES - The invention relates to a device for monitoring errors in undercarriage components of rail vehicles, having at least one acceleration sensor which works with an evaluation unit. At least one acceleration sensor is arranged on the undercarriage of the rail vehicle in such a manner that its direction of detection has at least one component parallel to the vertical axis (z-direction) of the rail vehicle. The invention proposes that the acceleration sensor is constructed in such a manner that it delivers a measuring signal which contains the signal portion corresponding to a ground acceleration, or represents a signal corresponding to a ground acceleration, and that the evaluation unit has a routine for testing functions of the acceleration sensor, the routine controlling an error signal if the measuring signal delivered by the acceleration sensor contains no signal portion corresponding to a ground acceleration. The routine also suppresses the error signal if this is not the case.

METHOD FOR MONITORING THE STATE OF A BOGIE OF A RAILWAY VEHICLE COMPRISING AT LEAST ONE WHEEL SET - A method for monitoring the state of a bogie of a railway vehicle having at least one wheel set, wherein the wheels of the wheel set are rigidly connected by an axle and have an approximately conical wheel profile, and signals corresponding to a sinusoidal run of the wheel set of the bogie based on the conical wheel profile of the wheels are filtered out of signals provided by sensors disposed on the bogie. The frequency of the sinusoidal run is determined relative to boundary conditions, such as the prevailing vehicle speed, and compared to a save value or range of values for the frequency of the sinusoidal run typical for the prevailing boundary conditions, wherein the deviation of the measured frequency from the saved value or range of values for the frequency is monitored.
